The gallery page I'm viditing has url rewrite enabled. I can visit the main
gallery page correctly, but when clicking on any album, the apache child
crashes.
After looking at an strace, it maybe caused by a incorrect database upgrade
from gallery (which asked my password during the upgrade, but I may have typed
it wrong).
Last part of the strace shows:
